You need to tell java it can use more memory then is available For example for maven itself you can # export MAVEN_OPTS=-Xmx2g
You don't really say what part of the build gives the error, could be maven itself, the java compiler, java process running the unit tests, many others, each of these may need different configuration to increase the allowed memory usage.
